Which .Figure l is a vertical longitudinal section of 4a device embodying one 'forni of my inventioii;,Fig. 2 is a vertical transverse section thereof taken on the line Q-Q of Fig. 1;' Fig. 3 is a plan view with the cover plate thrown back; and Fig; 4 is a detail horizontal sectional viewfonthe line 4-l of Fig."2.

This invention has relation to that class of devices employed for locking a valve closed or open, its especial purpose being to control the supply of liquid fuel to the internal combustion engine of a motor-vehicle, whereby the valve may be locked iii a closed position to cut otle the gasolene tank from the engine and thus prevent evil-disposed persons from ruiming the vehicle without authority, as more fully set forth.

In the drawing, a designates a suitable open-topped casing set down in a hole in the iioorvb of the motor-vehicle,l the upper edge or rim oi the casing being flush with the upper surface of the flooring, and a hinged lid c'"b'eing. provided to cover the casing, this` lid being also flush with the surface ot the flooring, so that the apparatus will not present any obstruction upon the licor.

Extending longitudinally through the casing'a, 'near its bottom, is the gasolene supply pipe Z .and mounted rotatably therein is a stop eock e of the usual torni. Ailixed to the upper end of the stein of the valve plug e' is a spur gear f, and securedbetiveen this spur gear and a shoulder-on the stein foi tho plug is a bottom plate g oi a frame adapted to be slid into and fout of the casing o through the upper open side thereof, said casing consisting additionally of an upright end plate la and a top plate z'.

The gear f meshes with a pinion iatlixed to the lower proJectmg end le oi' the key` .operated cylinder of any well knownulock of `Yale or permutation type. This key cylinder ismounted in the usual-key barrel l,-

and this key barrel is fastened to the 4lootin'i plate by screws m, The screws'mhold 4the key bari-cl in place.thefvlange,"'nl ,en -the key 4barrel being held tightly by said screws against the upper face of the top bar z' of thil removable casing.

The'ratio oi the gears and ils four to 50 one, so that a complete revolution ofi'tlie key cylinder with its gear y' serves to turn the plug one-quarter` and thus either opeiior close the cock, as the case may be. ll'ith each .revolution oi. the key cylinder, the key may be removed, as usual, from the lock to permit the cover plate c to be swung downwardly into place. To indicate whether the cock is open' or closed, I ailix thereto a rod o and extend the-same up through a screw y).

to the upper face of the top plate a' of the removable frame, the upper end of the rod being provided with an indicating finger Q, and the upper face of the top plate ye' being provided ivith suitable marks or symbols to indicate to the observer whether the cock is o en or closed. The screw 0 is tapped down tirougli the upper plate vz'V and bears cen-v trally against the uppei end of the plug e,

so that the plug may be tightened from time By removing these screws the 'frame may be 3'5 *removed from the casing, carrying ivith it yall the operating mechanism, so that the parts of lthe apparatus are easily assembled as Well as easily removed for repair and cleaning. To prevent surieptitious removal gn of `the mechanism from the casing, I piovide an'autoniatic locking device which insures the locking of tlie'rame as ivjell as all the connected parts iii the casing nlieiiever the valve plug is adjusted to closed position.

This locking` devicecmbodies a radial Aarm or arms s alixedy to the stem of the plug at .a point just under the plate g, so as to turn with the plug, the ends' of these `arms being adapted, when the plug isvturned ,to closed.' 10'0 position, to pass underlugs projecting in"- wardly from the side walls of the .casing a, thus rendering removal of the operating parts from the easing 'impossible Without .l

entirely dismantling -the apparatus. Having thus described my invention, what 'I lclaim is-w 1.1 In combination, arcasiiig open `-at upper 'enda fluid-supply conduit passing through the lower. end` of the casing, a framel 11o .slidableintoand' out 'of the upper sideof the casii` ig,"'ay Valve plu'grcar'ried 'bylsaid frame,
